Criticism was mostly aimed at the game's physics engine, [172] [175] though a consensus on the topic has been mostly unclear, with some defending the engine. [170] In a review of Rocket League 's beta preview, Ozzie Mejia of Shacknews praised Psyonix's approach to updating Battle-Cars using the PlayStation 4's hardware, describing the graphics ...
Supersonic Acrobatic Rocket-Powered Battle-Cars, colloquially known as SARPBC and officially abbreviated as SARP Battle-Cars, is a vehicular soccer video game for the PlayStation 3. The game was released in North America in October 2008, and in Europe in February 2009. The campaign mode of the game is made up of a series of varied mini-games ...
Model rocket motor classification. Motors for model rockets [1] and high-powered rockets [2] (together, consumer rockets) are classified by total impulse into a set of letter-designated ranges, from ⅛ A up to O . The total impulse is the integral of the thrust over burn time. Where is the burn time in seconds, is the instantaneous thrust in ...
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1] PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes (Zond 2 and Zond 3) starting in 1964.

de Laval nozzle. Diagram of a de Laval nozzle, showing approximate flow velocity (v), together with the effect on temperature (T) and pressure (p) A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, making a carefully balanced, asymmetric hourglass shape.
The engine is in the left background with a shield structure in the mid/foreground. A nuclear thermal rocket ( NTR) is a type of thermal rocket where the heat from a nuclear reaction replaces the chemical energy of the propellants in a chemical rocket. In an NTR, a working fluid, usually liquid hydrogen, is heated to a high temperature in a ...
Archimedes was presented on December 2, 2021, in a webcast by Rocket Lab CEO Peter Beck [ 4] as a fully reusable, gas generator engine using liquid oxygen (LOX) and methane as propellant, a departure from the company's previous Rutherford, which is electrically pump fed. He then stated that it had a thrust of 1 MN (220,000 lbf) and 320 seconds ...
